Title: Polishing method and device for silicone ball
Inventor: MURAMATSU KATSUTOSHI
IPC: B24B37/02
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To reconcile working quality and capacity to a high degree, and improve surface roughness. SOLUTION: An alkali solution is used as an abrasive solution to grind silicone balls W between a facing pair of lapped surface plates 2 and 3. Consequently the silicone balls W are ground while melted by the alkali solution and can be polished even by a small working load in a short working time. At least one side of the lapped surface plates 2 and 3 is made of resin. Consequently working force, received by the silicone balls W from the lapped surface plates 2 and 3 or an abrasive grain embedded in the surface plates, can be relaxed by the elastic deformation of the resin to improve surface roughness without detracting the shape correction effect of the silicone balls W.

Title: Power ripple suppression circuit for differential amplifier
Inventor: SATO HIROYUKI
IPC: H03F1/30
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To reduce the fluctuation of output voltage caused by the ripples regardless of the amplification degree of a differential amplifier by providing a voltage dividing circuit which divides the voltage of the power line of the differential amplifier and a circuit which supplies the divided voltage to an inverted or non-inverted terminal. SOLUTION: The voltage of a +B power line is divided by the impedance elements Z1 and Z3 and supplied to an inverted terminal (-) of a differential amplifier 1, and the voltage of a -B power line is divided by the impedance elements Z2 and Z3 and supplied to the inverted input terminal (-) of the amplifier 1. In such a constitution, the fluctuation components such as the ripples of both +B and -B power supplies, etc., are supplied to the inverted input terminal (-) of the amplifier 1. Thus a signal that lacks the voltage fluctuation and the in-phase component supplied to the inverted input terminal (-) emerges to the output of the amplifier 1. Therefore, it is possible to suppress the ripples superimposed on the power lines down to a desired level and the desired frequency without affecting the amplification degree of the amplifier 1.

Title: Signal acquisition method for gps receiver
Inventor: KAWASAKI KENICHIRO
IPC: G01S1/00
Filed: 1992-08-05
Abstract: PURPOSE:To make unnecessary a clock circuit for maintaining current time by performing catching operation with a matching filter on all possible satellites until a signal from at least one satellite is caught. CONSTITUTION:A code searching circuit 33 is a matching filter operating on an IF signal quantized with an asynchronous carrier, and the seaching of a code phase is performed at a high speed until a signal is caught after a power supply is turned on. Also, when CPU 16 receives a detection signal DET during the searching of a code phase at a certain carrier frequency, it judges that a signal from a satellite has been caught at the carrier frequency, and resets an RS flip-flop and at the same time performs the seaching of a phase with an I register 17 and a Q register 18 at the carrier frequency in which correlation has been detected to accurately seek the phase of a code. And in case a signal from a certain satellite could be caught after the searching operation has started, the satellite is set aside from the objective to start synchronous tracking operation.
